Question

Find the area of triangle with sides 35cm,54cm,61cm

Answer 1

Perimeter of the triangle = 150cm
SemiPerimeter of the triangle = 75cm

By Heron's Formula
Area = 
Area = 
Area = 939.14 

Answer 2

Let the triangle be ABC with a perpendicular drawn at D

Now,AB=61cm
BC=54cm
CA=35cm
CD=54÷2=27cm

(AD)^2+(CD)^2=(CA)^2
SO, (AD)^2+(27)^2=(35)^2
(AD)^2=35^2-27^2
(AD)^2=(35+27)(35-27)
(AD)^2=62×8
(AD)^2=496
(AD)=root over 496
Find the number then using the formula find the area of the triangle!
Hope this helps!
